To all whom it may volw/fwn.-

Be it known that I, IIENRIKA IVILi-IELMiNA' B iiin, a subject of the Czar of Russia and Grand Duke of Finland, and a resident of the city of I-lelsingfors, Finland, Russia, (whose post-ollice address is Skillnadsgatan 19, Helsingfors, Finland) have invented certain new and useful Improvements in Fountain-Pens, of which the following is a specification.

My invention relates to certain new and useful improvements in fountain-pens; and the object of my invention is to produce a pen in which the ink is automatically fed to the pen-point and the flow of ink is regulated by the amount of pressure on the'pen-point during the writing operation. By this means when heavy pressure is applied to the penpoint, and consequently a large amount of ink is re( uired, the feed will be increased to-meet this emand. When the pressure is light, the feed will be correspondingly decreased.

I will first describe my invention in connection with the accompanying drawings, wherein I show the preferred form thereof, and will then particularly point out in the annexed claims the particular parts and combinations which form the invention.

Referring to the drawings, wherein I show the preferred form of 1n invention and wherein the saine part is esignated' by the saine reference-numeral wherever it occurs, Figure 1 is a central longitudinal section of a fountain-.pen embodying my invention. Fig. 2 is a side elevation with the cover for the pen-point in position, showing the pen-point in dotted lines. Fig. 3 is a top plan view with tlie cover removed. Fig. 4 is a detached view of the end of the fountain-pen, similar to Fig. 1, showing, however, the regulator in its outer position.

1 designates a tube preferably formed of vulcanite or similar material. This tube is open at both ends and is provided at one end with a plugl, which on its inner end is formed with a projecting shoulder 3. The plug 2 is provided with an opening 4 bored therethrough to permit of the filling of the pen, and this opening is closed by means of a stopper 5. In the opposite end of the tube I provide a plug 6, lia-ving an inwardlyrojecting shoulder 7.

through its outer end, andthe plug is also provided with a central aperture 9, being formed near the rear end of the' plug witha The plug 6 is provi ed with a circular recess which extends into the plug l through the side of the lug. The plug at the front end is provide with a .projecting nipple 10, and 11 is a section of rubberI tube which embraces the nipple.

12 is a duct which extends from the end of the nipple to the pen-point and is connected thereto by means of the tube 11.

13 is a metallic ring which is inserted in the recess 8 and clamps the tube 11 in position. This ring loosely fits the aperture, and between tlie outer surface of the rinfr and the inner surface of the aperture is placed the pen-point 14.

15 is a lever pivoted at 16 in a slot 40, cut in the side of the tube of the lug 6, one end of said lever extending into tFe casing 1 and the other end extending out to the pen-point 14. The outer end of the lever is provided with a rubber tip 17, which is adapted to engage the top of the pen-point, as best' shown in Figs. 1 and 3. V

18 is a rubber tube, one end of which engages the shoulder 3- on the plug 2, and the other end of which engages the shoulder 7 on the plug 6. This tubeforms the reservoir for the ink. The inner end of the lever 15 stands just above the tube 18 and approximately at its middle point. From this it will be seen that when the en-point is pressed onto the paper to prodliice a heavy line the outer end of the lever 15 will be raised, which will depress the inner end of the lever against the tube and force the ink out to the pen-point.

Preferably and as shown `I provide a means for regulating the normal flow of ink to the pen. This is accomplished by forming the rubber tube 18 with an enlargement adjacent to the portion where it embraces the plug 6, through the side of which, it will be remembered, `the aperture 9 extends, and I provide a sliding regulator 19, mounted in a groove 2() in the plug 6, the free end of the regulator resting against the tube. When the regulator is pushed, to its inner position, as shown in Fig. 1, the supply of ink to the en will be totally cut off, and thus prevent eakage. .When, however, the regulator is drawn outwardly, it will gradually open to passage tothe aperture 9 until it has fully opened this aperture, as shown in Fig. 4.

In order to cause the pen to immediately begin to feed when the writing is commence I provide a spring 21,(showii in dotted lines in Fig. 3,) one end of which is secured to the right-angled turn, so that it extends outil inner side of the casing 1 by a rivet 22 or IOO IIO

other means7 and the other end of whichisprovided with.. a. head 23,.. which" extends to t iepen-point. preparatory toJ they beginning of the writing operation.

From the above description it'i's'beli'eved that the operation of my invention will be fully understood'. I'd'esirge to call attention, however, to the fact' that' thepen-point can be readilyy removed and any other pen-point substituted therefor.

While I have described what I believe to bef-thepreferred form of'm invention, I de-k sire to have it understood' t' latmany changes maybe made'in the form, construction, land arrangement of parts 'without departing from the spirit of my invention. v VWhat I claim as new', and desiret'o `secure byA Letters Patent7 ispl'. In a fountain-pen, the combination of' a casing, of an elastic reservoir within said casing, a plug closing one end of said casing, a point mounted in said plug, al lever pivoted in said plu0r and `having one end resting on the pen-point and' .the other" on the elastic reservoir, whereby pressure on the pen-point will compress the reservoir and force the ink to the pen-point.

InI afountain-pen the combination or a penliolder carrying a pen, a reservoir in the older, vany inkchannel connectedY to' reservoir and deliveringink from reservoir to pen, and means' operated by the bending of the pen to force ink from the-reservoir to the pen. 4c.A In a fountain-pen the combination of a enholder carrying a pen-7 a flexible reservoir 1n the holder; an ink-channel' connected to reservoi'randv delivering ink from reservoir to pen, and meansoperated by the bending of the pen to force ink from the reservoir to the pen.

In testimony whereof If havesigned at the city of H'elsingfors this 12th day of June,
